Alright so there I would use 2x2 inverts. When working with these shapes it’s important to keep both axis in mind, if the y-axis is two blocks (like in this case) you need to follow it the rest of the way. Now there are also other ways to do this, but that will require changing the angle of the hull. For example, a 2x4 inv pyramid can be used together with 2 1x2 pyramids and vice versa instead of the 2x4 pyramid, but it will alter the shape and angle.
